Hi, I'm hoping someone may be able to help me. I did ww years ago and was very successful. I kept the weight off for years put gained weight when I stopped smoking. I tried the new pro point system but never lost weight on it. I would like to do the old points again. I found 3 cookbooks I had stashed away but is there a difference between pure points, switch and 123 success. Also I have searched eBay but can't find any starter packs for sale telling me how many points I should be on or how to work out points. I used to have a calculator but got rid of it. Maybe you might know an app or web page that could help me.. thanks Sinead
